The first total synthesis of a bioxanthracene (-)-ES-242-4, an N- methyl-D-aspartate receptor antagonist

Bioxanthracene (-)-ES-242-4 has been synthesized from oxidative dimerization of a naphtopyran which was derived from an α,β-unsaturated lactone and methyl 2,4-dimethoxy-6-methylbenzoate through tandem Michael- Dieckmann reactions.
